Check the spark plug gap using a wire-
type feeler gauge.
u If adjustment is necessary, bend the
side electrode carefully.
The gap should be:
0.031 - 0.035 in (0.80 - 0.90 mm)
6.
Make sure the plug washer is in good
condition.
7.
Install the spark plugs. With the plug
washers attached, thread the spark plugs
in by hand to prevent cross-threading.
8.
Tighten the spark plug:
● If the old plug is good:
1/8 turn after it seats
● If installing a new plug, tighten it twice
to prevent loosening:
a) First, tighten the plug:
NGK: 3/4 turn after it seats.
DENSO: 1/2 turn after it seats.
b) Then loosen the plug.
c) Next, tighten the plug again:
1/8 turn after it seats.
NOTICE
An improperly tightened spark plug can damage the
engine. If a plug is too loose, a piston may be damaged. If
a plug is too tight, the threads may be damaged.
9.
Install the parts in the reverse order of
removal.
u When reinstalling the spark plug caps,
take care to avoid pinching any cables
or wires.
